brake flexi pipes, v.silly question.

[Paulo.dicanio]

Hi all.

I've just replaced the front calipers on my chin 500. Having gone to refit the flexi pipes into the caliper they only screw into the caliper about half way. There is recess in the caliper where it looks the flexi pipe should screw right into onto a copper washer? Can someone confirm for me this is the case? I originally removed the calipers a few months ago as part of the tidying project, hence why I can't remember how they should fit.!!

The flexi pipes are the original ones I removed from the car, the calipers are
Dca 086/087 as specified by brake international.

If anyone can tell me why I'm being such a doughnut I would be eternally gratefull!

There are no copper washers needed. The flexi pipes just screw into the caliper. If all threads are clean they should just screw in by hand and then a quick nip up.

Are you sure the flexi threads are the same as your new calipers.

[Paulo.dicanio]

The flexi pipes are the correct thread, just the threaded section is too long ad when tightening there is still about a centimetre of exposed thread. Didn't seem right to me?

As long as the hose has seated at the base of the caliper, thats fine. Its there where the seal is made. It is quite normal that an amount of thread extends out of the caliper.

Cool beans, that solves that. Thanks for the help

What he said, the seal is at the tapered end of the pipe if still in doubt post up a pic

As everyone else says seal is generally at the taper. Two points to consider though

1 If the thread is to long and you have enough room use a lock nut on the thread and calliper.
2 Check inside the calliper where the fluid flows - I had a similar problem and found the caliper requiring shorter thread was for banjo fittings and the fluid hole in the calliper is half way up and not designed for the male fitting IYSWIM
Good luck
